JOHN A BASSETT, or SALEM, MASSACHUSETTS.

IMPROVED APPARATUS FOR CARBURE TING. AIR.

Specification forming part of Letters Patent No. 47,272, dated April 18, 1865.

, To all whom it may concern.-

Be it known that I, J OIIN A. BASSETT, of Salem, in the county of Essex and State of Massachusetts, have innented a new and useful Improvement in Apparatus for'Vaporizing and Aerating Liquid Hydrocarbons; and I hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, of which- Figure 1 is a sectional view. Fig.2 is aplan, and Fig. 3 section of carbureting-tubes.

The nature of my invention consists in carbureting air by bubbling it through benzine underpartially-submerged horizontal tubes, the lower part of which are open, and the edges of which are serrated, placed in achamher or vessel, which is'connected with a reservoir of hydrocarbon liquid arranged so as to maintain a constant level in the evaporatingchamber and a proper submersion of the tubes and it further consists in combining with this arrangement a pump or power meter having a single diaphragm and producing acontinuous current of .air.

To enable others skilled in the art to make and usemy invention, I will proceed to describe the same.

I construct the chamber or vessel A of any suitable material, galvanized iron being preferred, and provide it with a holder, B,working in the seal '0, for the purpose of securing a steady flow of gas to the burners. In the lower part of the chamberA, within a few" inches of the bottom, I place parallel rows of tubes 1), about three-fourths of an inch apart. These tubes are more properly half-cylinders, ;l with the open part under the level of the'beuzine. The length of the tubes on both sides is serrated or out like saw-teeth, and the level of the bcnzinc should be adjusted to the top of one-half the height of the tubes. The air enters these cylinders at one end of the vessel A, and, passing under.the hood E, into which all the tubes are soldered, goes simultaneously through all the tubes and bubbles out at the sides through the benzine, the ob jcct of the teeth or serrations being to distribute the air 'and cause it to separate into fine bubbles,which carburcts it thoroughly by mixing it intimately with the' benzine. The henzinc is to be kept at the proper .level in the chamber Aby a continuous flow from the reservoir F when the evaporation is going or. The reservoir F is placed at the side of the chamber A. At the level at which it is desired to keep the bcnzinc, an opening, G, is

made in the partition u hich separates the reservoir from the chamber. This opening com municates by a tube, H, above the level of the benzine in the reservoir. Another opening, I, is made below the level of the henzine, through which it passes into the chamber. .When the opening of the tube H is covered with benzine, no air can get mto the reser oir, but when it is uncovered air will pass up the tube, and thus allow a sufficient quantity of ,bcnzine to pass into the chamberA to maintain the level. The opening I is controlled by the valve K, which is to be closed when the reservoir is to be filled. The reservoir may be filled through the opening L, which should be closed by a tight screw-cap. A continuous current of air is forced into the chamber A by the powermeter M. This is made by inclosing in a sheet-iron case, N, a 'singleflexiblc diaphragm,

U, of leather or rubber, and covering it withquarter-shields of metal, .to which the shaft P is secured by the cross it. case are valve-seat openings, which communi- Gate with the space on each side of the din-v phragln. The seopenings are coveredby the valve S. This valve is connected by levers and eccentric to and is actuated from the shalt T. The shaft P is connected by a crank. or cam to the shaft T, so that by the rotary motion of the shaft T a reciprocating motion is communicated to the diaphragm and a contin uous current of air is forced into the carburetor through the pipe U. The valve S is covered by a case, and the admission of the air is controlled by a valve which is put in motion by the rise and fall of theholder acting through levers. This val vc regulates the admission of the air so as to keep the holder full and no more than full. The shaft T is a portion of a train of wheelwork which is put in motion by a weight, and which may be wound up so I prefer to use a hydrocarbon which is entirely evaporable;

as to run for several hours.

but if any is'used which is liahleto leave a rcsidium which cannot be aerated, it may be drawn ofl' by a siphon connected with a reservoir. V a

The several parts of this apparatus are sim- On the top of the plo, d iii-able, not expensive, andnotliable to get out of order; It is combined in such a I way-as to be verycompact, and in its workbe increased or diminished easil and affords a ready means of determining. the power of the. apparatus.

Having thus fully described the nature of my intention, what I claim as new, and desire to secure by Letters Patent, is

f 1. The general arrangement and construction of the apparatus, as shown and described. 2. The carburation of air or gases by the submerged serrated tubes,in combination with the reservoir, substantially in the manner described;

3. Thecombinatiou of a power-meter, constructed substantially as described, with an apparatusiused to aerate and vaporize liquid hydrocarbons, the whole operating together in the manner and for the purpose substantiallyas'setforth.
